doNextIteration
boolean doNextIteration(int iteration,
double f_last,
double f_current,
double[] gradient,
double[] direction,
double alpha,
Time t)
- This method allows to decide whether to do another iteration in an optimization or not.
- Parameters:
iteration
- the number of performed iterationsf_last
- last value of the functionf_current
- current value of the functiongradient
- the gradient of the functiondirection
- the last direction of the optimizationalpha
- the last step sizet
- a time object measuring the time that has been elapsed in the optimization
- Returns:
true
if another iteration should be done
